چکیده

We use the theory of vertex operator algebras and intertwining operators to obtain systems of q-difference equations satisfied by the graded dimensions of the principal subspaces of certain level k standard modules for ŝl(3). As a consequence we establish new formulas for the graded dimensions of the principal subspaces corresponding to the highest weights iΛ1 + (k − i)Λ2, where 1 ≤ i ≤ k and Λ1 and Λ2 are fundamental weights of ŝl(3).

00 6 Intertwining vertex operators and certain representations of ̂ sl ( n )

We study the principal subspaces, introduced by B. Feigin and A. Stoyanovsky, of the level 1 standard modules for ̂ sl(l + 1) with l ≥ 2. In this paper we construct exact sequences which give us a complete set of recursions that characterize the graded dimensions of the principal subspaces of these representations. This problem can be viewed as a continuation of a new program to obtain Rogers-Ra...

Combinatorial constructions of modules for infinite-dimensional Lie algebras, I. Principal subspace

This is the first of a series of papers studying combinatorial (with no “subtractions”) bases and characters of standard modules for affine Lie algebras, as well as various subspaces and “coset spaces” of these modules. In part I we consider certain standard modules for the affine Lie algebra ĝ, g := sl(n + 1, C), n ≥ 1, at any positive integral level k and construct bases for their principal s...

Vertex - Algebraic Structure of the Principal Subspaces of Certain a ( 1 ) 1 - Modules , Ii : Higher Level Case

We give an a priori proof of the known presentations of (that is, completeness of families of relations for) the principal subspaces of all the standard A (1) 1-modules. These presentations had been used by Capparelli, Lepowsky and Milas for the purpose of obtaining the classical Rogers-Selberg recursions for the graded dimensions of the principal subspaces. This paper generalizes our previous ...
